The Schedule referred to in these Letters Patent and making pari: oi the saine.

I, ISAAC STEAD, ot' Philadelphia and State of Pennsylvania, and I, HENRY HOLCROFT, of Media, county of Delaware, and State of Pennsylvania, and also l, FRANCIS 1t. PnAnsoN, of Germantown, county of Philadelphia and State of Pennsylvania, have jointly and together invented certain Improvements in Seli'- Acting Mules for Spinning Yarns, ot' which the following is a specification.

` Natura and Object of the Invention..

The first part of our invention relates to the combination and peculiar arrangement of a ratchet-wheel, plate or diskwheel, catch and stud, operating a slotted disk fastened on and to a shaft having on it several cams for moving the various clutches, levers, and cams, to produce various movements requisite in a self-acting mule, which will be hereafter explained.

The second part' of our invention relates to a pecnliar mechanical arrangement for operating the catch of the above-mentioned ratchet-wheel by a worin and worm-wheel, (called the twist\vheel,) to produce the movements for an increased speed ofthe spindles, (for twist,) also for the hacked". The third part ot our invention relates to anarrangement for operating the above-mentioned catch and ratchet-wheel by the outward movement ot' the carriage for the purpose of stopping it when the carriage has run out the full length oi' the stretch, and the arrangement to operate the said catch by the inward movement of the carriage to produce the movement to run the carriage out, and gear and twist-wheel and other parts that are necessary to gear when the carriage begins to run out.

The fourth partot' our invention relates to an arrangement for operatingr the taller, whereby we are enabled to place the topping or building-rail at the top of the traine.

The fifth part of our invention relates to a peculiar arrangement ofmachinery for building the cop or bobhn, which we place on the taller-shaft.

details 0f' the The otheriigures in this sheet are sections and parts in detail.

Same letters and gures in the drawing refer to like' )arts l A is the frame of the machine, which frame should be substantially constructed to resist vibrations of the operating parts. g

1S is the driving-pulley, which is hung on the main shaft G ofthe machine, and from the latter motion is communicated to the operating parts.

D is the carriage.

E is the shaft to be attached to the front roller, and 0n this shaft is hung the sleeve-stud, F, on which the worm or twist-wheel Gr is hung, and also the ratchet clutch H.

The construct-ion ot' the ratchet-clutches is shown in detail on sheet 4.

H is a sleeve attached to the arm H1.

On the lett of the sleeve is a small lug, a", which impinges against the trame A. l

Inside ot' the sleeve 1I is a collar, C, and on one end of the collar are formed ratchet-teeth.

This collar is pinned or keyed fast to the shaft E.

The hub of the wheel D is turned down to the size of collar c", and formed on the end with ratchet-teeth, to gear Iin those in collar c".

lhe sleeve H iro'ects over and against the collar4 l J e turned on the hub ot' the wheel D'. The ratchet-clutch H2 on shaft J is constructed the same as above.

Attached to the arm ofthe sleeve H on the' shaft E is one end oi' a lever, u, the other end resting on the pin p' in lever F. (See sheets 1 and 2.)

lhe shaft I forms a carrier het-weon shaft E and shaft J, and on the shaft J is placed the worm K, for driving the worm-whecl G.

On the shaft J is placed thel scroll-pulley L, which is used to draw the carriage out.

On the otherend of this shaft J is `the ratchetfchiizh H", for throwing the shaft and scroll in and out of gear.

On the main shaft C is hung pulley M, i`or giving an increased dlcs tor twist.

Fastened to this grooved wheel is the cone frictionpulley N, which lits to and is driven by the cone fricti0nhox lt, formed in' the main driving-pulley O is a spur-wheel, having internal cogs 0l' teeth,

the large grooved speed to thc spinand driven by two small pinions, one on the shaft O, and the other on a stud fastened to the frame A, the intermediate pinion being used as a carrier-wheel.

On and fastened to the wheel is a cone frictionbox, l. (See detail, sheet 4.)

On thc shalt C is hung,r loosely the piuion-whecl1.

To the hub of this pinion, on one side, is attached` a cone friction-pulley, N', and on the opposite side ofl this pinion, and fastened to the hub, is a grooved pulley, Q, and cone friction-box R.

' On and fastened to the shaft O is the cone friction.

vone side of and fastened to this wheel is a cone friction-box, BJ.

On-tlre opposite side of this wheel is along hub, on which hub is fitted loosely thev disk V, and keyed to the hub is the ratchet-wheel W.

On the end of the hub of the wheel U is turned a groove. (See detail, sheet 3.) y

On ,the extreme right end of shaft Y is a conefriction-pulley, Nf", which is fastened to shaftY and gives motion to the scrolls L and L", which are used to draw the carriage in, one being used as a balance-,scroll to steady the motion of the carriage. One scroll unwiuds as the other winds up.

On and fastened to shaft G' is the slotted diskl wheel l.

The hub 1 of this disk forms and operates as a cam to shift the friction-box on the wheel U, to operate scrolls L and L" on shaft Y.

On the shaft C' is fastened the cam 2, for gearing l the twist-wheel G.

On the same shaft G is the snail-cam 3, for shifting pinion and cone N' and cone-box It on shaft C.

On and fastened to shaft C is cam 4, for gearing the ratchet-clutches H and H2.

On and fastened to the left end of shaft C is the cam-5, for shifting the' grooved pulley M.

All of the cams on the shaft O are fastened by setscrews, as theyl require to be nicely adjusted.

On and fastened to shaft E are two grooved pulleys, one larger than the other, the smaller one acting as driver for the spindles when the mechanism for giving increased speed is in gear forI twist.

a representsf'the faller-shaft, on the right end-of which is cut a screw-thread.

b represents a ratchet-\vl1eel,iu the hub of which is cut a sci-ewftluead to fit the thread out on the fallershaft a. y

To the left of the ratchet-wheel. bis a collar, c, sliding'on a feather setin the taller-shaft a.

Diagonally across the periphery of this collar is a feather or wing. (See detail, sheet 1.)

Further to the left, and next to the sliding collar c, is-the quadrant ql, for the purpose of drawing the fallver down.

On the hub of this quadrant is a small shell or projection, n, which impinges against the feather or wing on collar c. 4 l

The quadrant'd, being loose on the faller-shaft, the shaft gets its motion from the collar c. From this quadrant passes the cord o to a pulley on the drum-shaft e of. the carriage. y

Extending from the hub of this quadrant is an arm, j', to the end of which is pivoted asmall arm, q, in one end of which .s a small roller.

As the cari iage moves in, the roller runs on the slip or copping-ral h, which is pivoted on a stud, i, at the left end of the frame A. (See sheets 1 and 2.)

To the oth :r end of the copping-rail is attached a vertical scre\.` which is fitted to a nut fastened tothe frame A, and on the top of the screw is a small ratchet-wheel, k. v

To the left of the quadrant d, and fastened tc the faller-shaft a by a set-screw,'is a small cam, e.

On the outer end of the frame A, on a stud, is the catch b', for working the ratchet-wheel b.` On one end of this catch should be a spring or weight.

YThe disk-wheel V and catch lr are formed as shown in detail, sheet 3.

At the top of the disk is vthe catch r, and at the bottom of the disk is fastened a piece, z', toact as a counter-balance. l v

The small pin atthe top of the disk is to prevent the catch from falling out as the disk revolves.

rl'he vpin or stud c is fitted to work in the slots of "the disk 1. v v On sheet 4, to the'left, is shown the lever tw, on one' end of which is hung a weight, and on the same end is also a stop-lug, k'.

On the other end and on the top are two V-shaped lugs, g'and c".

On the same end is pin x, and from this pin is a.

rod, z, connected at its other end to the lever y. (See By this rod z connection is made from the sheet 3.) twist-wheel G.

On the .opposite end of the same stud tov which lever y is pivoted is a lever, lm, which connects with lever/n'. (See sheets 1 and 4.)V This forms the connection from twist-wheel Gr to clutch-box H on shaft E. i On sheet 4 may be seen the connecting-rod or bar f', one end of which rests on the lever w, the other end being connected to lever b' by afsmall screw, on which it works freely. 1

To the lever b" is fastened a spiral spring, s'.

On the bar f is a small lug or stop, o', and just above this barl is4 the lever a', pivoted on atstud fastened to the frame A, that end of the lever marked a. being the heavier to insure lit always resting ou the bar f.

Hung on a small stud fastened to the carriage D` is a small lever, d', resting against the pin v'.

Also, to the carriage D (which is shown on sheet 4 by dotted lines) is hung ona small stud the lever c. This lever rests on the bottom of the carriageframe. (See sheets 1 and 4.) l

The twist-wheel G we construct withxholes in the face. Into each of these 4holes we tap a screw-thread,

and into one of these holes we screw a pin or stud, 75",.Y Y'

and around the periphery of the hub, on the other side. of the wheel, screw-holes are drilled.

` Into two of these holes We screw pms orlugs a and af, one for thetwist and the other for the backoff. (For a fuller description of the twist-wheel, see patf.

ent granted November 26, 1867, to F. R. Pearson.)

The operation of our improvement is as follows: y

The carriage, as shown in the drawing, is supposed to be running out, and all of the parts are in gear as when the carriage commenced to moveout.

The rst move made is` the pin h in twist-wheel, which liftslever m, and this raises lever n from catch-pin p on level' F', which dsengages the ratchet? clutch H on shaft E and stops the front roller, which has given out sufficient slubbing for one stretch when spinning woolen yarn.

If cotton yarn is being spun, the front roller continues to run 'to the full end of the stretch of the l After thev slubbing is ont of gear the next move is hy the pin a in twist-wheel, which raises lever y, causing the connection-rbd z' to move lever w, raising' lug 7c', which allows catch r to engage the ratchetwheel WV, (which has a continuous motion :in the direction of the arrow, see sheet 4,) and carries the disk V, which then makes one revolution, and, through the pin 'L7 and disk 1, moves the cam-shaft C one-fifth of a revolution, the disk 1 being divided into live equalv parts. v

The Vcam 5 is so adjusted that spring s" will fo'rce lthe cone-clutch on `pulley M into the clutch-box in pulley B, when it becomes the driver, and will give the increased speed to the spindles, the object being that time may be gained in` puttingv in the twist, it being understood that the pins or lugs'in the twistwheel are movable, and we are able to give any length of slnbbing desired; and the increased speed maybe p nt on at any suitable part of the stretch either before, at the same time, or after the slubbinggear is thrown out, all of' which are at the option of the spinner.

The next and second move made by the disk on cam-shaft is .to stop the carriage, which is done, by the lever c'" as the carriage is moving out pressing lever b', which moves bar f', and as the V-shapcd lugs r' and q on lever 'w and bar f press against one another, the balgibeing prevented fronr rising by the 'hub g', will raise the lug k', as before described, and give to the disk V motion, which shifts the calnshaft C', and causes cam 4, through the lever F and ratchet-clutch H2 on shaft J, to disengage scroll L and stop the carriage.

The twist-wheel, continuing to turn the pin a', moves lever y, and, as before described, gears and moves slotted disk-wheel and cam-shaft, and the snail-cam' moves leveru; and through this lever the cone-clutch N and R on shaft C' are geared with the internal spur-wheel O, which reverses the motion of grooved pulley Q; andthe band S reverses the spindles for the back-oli; and at the same time laps the band() around the drum on shaft and raises the arm f on quadrant d. (See sheet 1.) The roller in short arm g then rests on the building-rail h.

The movement of the quadrant moves the collar c, which moves the faller-shaft a, and as the carriage moves out each stretch the ratchet-wheel b will com e in contact with the catchb', and as it revolves will move the `collar c from the quadrant cl, and the faller will move less at each', stretch as the cop or bobbin is filling .upon the spindles.

As the carriage runs in the arm q will run down on the rail h, which lets the arm q down and raises the faller.

At the inward part of each stretch a catch will move the ratchet-Wheel k, which raises the sliph gradually till the bottom of the cop or -bobbin is made7 the ratchet and slip being old and well known by those accustomed to operating on self-actin g mules.

Inthe backing-off'and drawing down of the faller the cam e on faller-shaft will trip the lever aand disengage the end of it from the lug o' and bar f',-

wheu the spiral spring s' will draw it back, and as it is being drawn back it will depress the lug g and raise the lug It on the other end of lever w, which allows the. cptch to agaiuengage the ratchet-wheel and give mot on to the slotted disk l.

The hub of this disk lis so adjusted that it will then allow the spring/w pressing against frame A to shitl".` thefforked lever, andthrough the hub and lever v the cone-box on wheel U is forced on the cone-pulley N, which gives the requisite motion to the scrolls L' and L" to draw the carriage in.

As the carriage is running in tlle winding of the yarn on the spindles donc by a quadrant and chain on the drums-shaft of the carriage, which arrangement is not shown in the drawing, as it is old and in general use on self-acting mules.

The next move is to gear the 'head and start the carriage out, which is as follows:

The pin 'in the lever d' on the carriage will, as the carriage moves in, press the lug e on lever w, which disengages the catch r, and motion, as before, is communicated to cam-shaft C and the cam 4, and clutches H and H2 on the shafts J and E are engaged and-give motion to the scroll L to draw the carriage out, and also to shaft E, which gives motion to the front roller and gives ont the slubbing for the next stretch.

The ,cam 2, bym'eans-of the lever h', at this move of the disk and cam-shaft, also gears the twist-wheel, and the snail -cam 3 and lever a gear the coneclutches N" and R" on main shaft, which gives motion to the spindles.

The'head is now geared complete for the stretch, and the movements then follow as above described. First, the -slubbing is thrown out of gear, the increased speed is pnt on, the carriage is stopped, the

back-ofi' is performed, the scroll for drawing iu the carriage is geared, and the carriage is run in and geared, as before described.
